python正确登录后无法获取wordpress Dashboard

我想创建一个脚本，在使用我的组合登录后返回 wordpress 仪表板，如下所示：（屏幕截图）

所以我创建了这个脚本

import urllib, urllib2, os, sys, requests , re
site = 'http://example.com/blog/'
username = 'username'
password = 'password'
url = site + '/wp-login.php'
req = urllib2.Request(url)
headers = {
"User-Agent" : "Mozilla/5.0 (Windows; Windows NT 6.1; WOW64; rv:2.0b2) Gecko/20100720 Firefox/4.0b2",
"Accept" : "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Accept-Language" : "es-es,es;q=0.8,en-us;q=0.5,en;q=0.3",
"Accept-Charset" : "ISO-8859-1,utf-8;q=0.7,*;q=0.7"}
data = [
("log",username), 
("pwd",password), 
("testcookie",1), 
("submit","Log In"), 
("redirect_to",'http://example.com/blog/wp-admin/'), 
("rememberme","forever")]

req = urllib2.Request(url, urllib.urlencode(dict(data)), dict(headers))
response = urllib2.urlopen(req)
the_page=response.read() 
with open('result.html', 'w+') as file:
     file.write(the_page)
response.close()
print 'done'

我收到的是登录页面，而不是我的 WordPress 仪表板：（屏幕截图）

我用错误的组合测试了脚本，它返回登录页面，并出现如下错误：（屏幕截图）

知道如何获取仪表板吗？非常感谢您的帮助 ps：正确登录的 dict(response.headers) 是：

我玩了一段时间，发现了一些对我有用的东西。
